1.1.1 GENERAL INFORMATION
(1) Specific features
The “Mitsubishi Daiya” room air-conditioner: SRK series are of split and wall mounted type and the unit consists of indoor unit and
outdoor unit with refrigerant precharged in factory. The indoor unit is composed of room air cooling or heating equipment with opera-
tion control switch and the outdoor unit is composed of condensing unit with compressor.
(a) Inverter (Frequency converter) for multi-steps power control
¡Heating/Cooling
The rotational speed of a compressor is changed in step in relation to varying load, interlocked with the indoor and outdoor unit
fans controlled to change frequency, thus controlling the capacity.
¡Allowing quick heating/cooling operation during start-up period. Constant room temperature by fine-tuned control after the
unit has stabilized.
(b) Fuzzy control
¡Fuzzy control calculates the amount of variation in the difference between the return air temperature and the setting temperature
in compliance with the fuzzy rules in order to control the air capacity and the inverter frequency.
(c) Remote control flap
The flap can be automatically controlled by operating wireless remote control.
¡Air scroll (AUTO): Flap operation is automatically control.
¡Swing: This will swing the flap up and down.
¡Memory flap: Once the flap position is set, the unit memorizes the position and continues to operate at the same position from
the next time.
(d) Self diagnosis function
¡We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation as
follows.

The piping length is 7.5m.
(2) The operation data are applied to the 220/230/240V districts respectively.
(3) The refrigerant quantity to be charged includes the refrigerant in 15 m connecting piping.
(Purging is not required even for the short piping.)
If the piping length is longer, when it is 15 to 25m, add 20 g refrigerant per meter.
